Silver 120 reflects Wolfgang Tillmans’ exploration of abstract and cameraless photography. Starting in 1992, the Silver series compiles experimental work that celebrates ‘the process’. In the series, silver nitrate-coated paper is exposed to a wide range of processes such as light, salts and chemicals, resulting in unpredictable marks, colours and shapes. Traces left on the paper shift the attention away from a photographic rendering to a deep sense of materiality. source
